Fact!

For the Lord is good; His mercy and lovingkindness are everlasting, His faithfulness [endures] to all generations.
PSALM 100:5 AMP

3 very specific, but very fundamental statements. First, The Lord is good: it is not a function of what your physical eyes see or the summary of your life's experiences; God is always good. It is his nature to be good. It is his attribute to do good, it is an aberration for evil to be associated with God. Sin has itself opened the doorway to evil, and with ain comes the natural consequences of disease, sickness and death. But it is clear: God's original plan did not include any of these.

Second, his mercy and lovingkindness are everlasting. What I get is not a function of what I do or who I know but on who God is. It is his name and nature at stake here. Some may plead degrees, others may plead connections. Others may plead possessions, but I am  reminded of the futility of it all. David was an adulterer, a murderer, a lover of women; yet God's sure mercies would not let him go. Tell me, which one would you rather have: mighty acquisitions or gleanings of God's mercy?

Third, His faithfulness [endures] to all generations. Yes, generations can testify of God's amazing faithfulness. Ask the children of Israel, beneficiaries of a promise made to their ancient forefather, and to this day, still working as promised. Ask David, promised an eternal kingship, and God breaking all protocol to ensure that over the house of Judah, who was not even the first  son, or the second, yet producing the king of Judah since the time of David, both in the physical and the spiritual realm through Christ.

Indeed, God can be trusted. Years do nothing to his memory or his promise. He isn't like man given to lapses of memory or subject to economic realities; he is King over all, he is Lord over all, and  the reality of His Word has been settled long before the reality of this present existence ever came to be. His time of favour is here.
